Just installed skyrim and played for about 3 hours. Only previous games are SWTOR and GW2.
Man alive, this is great. I thought the graphics in SWTOR were near cinematic, but they are cartoonish compared to skyrim. And I really loved the play action in GW2 (you can dodge and roll), but it does not have skyrim's crouching & sneaking.
A real strength of GW2 is that in PvP, all players are scaled to a more or less even level. And if a high level player returns to a lower-level area, he is debuffed to match the environment. Dunno if skyrim has anything similar, but since I'm only level 2, that's not yet an issue.
Probably my favorite bit so far was discovering that I could clear spider webs with my weapon in order to unblock a tunnel. No cheater highlights or targets to give it away. So lifelike, it takes the play to an entirely new experience.
Now if I can only train myself not to respond to attacks by automatically pressing "1" (in GW2, the basic attack skill).
